Age‐Related Osteogenic Potential of Mesenchymal Stromal Stem Cells from Human Vertebral Bone Marrow
Mesenchymal stem cells (MSCs) residing in bone marrow (BM) are the progenitors for osteoblasts and for several other cell types. In humans, the age‐related decrease in bone mass could reflectExpand
Marrow-isolated adult multilineage inducible (MIAMI) cells, a unique population of postnatal young and old human cells with extensive expansion and differentiation potential
We report here the isolation of a population of non-transformed pluripotent human cells from bone marrow after a unique expansion/selection procedure. This procedure was designed to provideExpand
Low oxygen tension inhibits osteogenic differentiation and enhances stemness of human MIAMI cells.
We recently reported the isolation of a unique subpopulation of human stromal cells from bone marrow (BM) termed marrow-isolated adult multilineage inducible (MIAMI) cells, capable of differentiatingExpand
Anabolic or Catabolic Responses of MC3T3‐E1 Osteoblastic Cells to Parathyroid Hormone Depend on Time and Duration of Treatment
We have investigated signaling (cAMP) and anabolic responses (mineralization of extracellular matrix [ECM]) to parathyroid hormone (PTH) in long‐term (30 days) cultures of MC3T3‐E1 cells, a murineExpand
Gap-junctional communication is required for the maturation process of osteoblastic cells in culture.
Osteoblastic cells in long-term culture undergo a phenotypic maturation process leading to extracellular matrix (ECM) production and bone nodule (BN) formation. Cell-to-cell communication via gapExpand
Inhibition of Gap-Junctional Communication Induces the Trans-differentiation of Osteoblasts to an Adipocytic Phenotype in Vitro *
Osteoblasts and adipocytes are thought to differentiate from a common stromal progenitor cell. These two phenotypically mature cell types show a high degree of plasticity, which can be observed whenExpand
24R,25-dihydroxyvitamin D3 promotes the osteoblastic differentiation of human mesenchymal stem cells.
Although 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3] is considered the most biologically active vitamin D3 metabolite, the vitamin D3 prohormone, 25-hydroxyvitamin D3 [25(OH)D3], is metabolized intoExpand
Parathyroid hormone stimulates bone formation and resorption in organ culture: evidence for a coupling mechanism.
We have developed an in vitro system, using embryonic chicken tibiae grown in a serum-free medium, which exhibits simultaneous bone formation and resorption. Tibiae from 8-day embryos increased inExpand
2-Methoxyestradiol induces G2/M arrest and apoptosis in prostate cancer.
Few therapeutic treatment options are available for patients suffering from metastatic androgen-independent prostate cancer. We investigated the ability of the estrogen metabolite 2-methoxyestradiolExpand
Human bone cells in culture metabolize 25-hydroxyvitamin D3 to 1,25-dihydroxyvitamin D3 and 24,25-dihydroxyvitamin D3.
Bone cells respond to 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) for mineral mobilization and contain receptors for 1,25(OH)2D3. We report here the expression of 25-hydroxyvitamin D3 (25 (OH)D3)Expand
